Flight dynamics

Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.

In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.

Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.

Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.

List auf Sylt

List auf Sylt (known as List until 31 December 2008) is the northernmost municipality in Germany, located on the North Sea island of Sylt close to Denmark in the district of Nordfriesland in the state of Schleswig-Holstein.

Etymology

List derived from the Middle Low German Liste (ledge, bar or edge).

History

List was originally a Danish settlement. It was first mentioned in 1292 (Lystum). The original village was destroyed by the great flood of 1364. The settlement was rebuilt further east from the previous location. In the mid-15th century, a church named St. Jürgen was mentioned. In a treaty of 1460, Schleswig and Holstein were linked to the Danish crown, but List remained part of the royal enclaves, small areas of the Kingdom of Denmark situated within the Duchy of Schleswig, but directly controlled by the Danish king.

From the 16th century, the people of List mostly made a living from Oyster farming, raising sheep and collecting and selling gull eggs. At the time, List was an important protective anchorage. In 1644, a Swedish-Dutch fleet of 26 ships commanded by Admiral Thijssen was attacked in the Lister Tief and defeated by Danish ships commanded by king Christian IV of Denmark. The anchorage north of today's town was named Königshafen to honour this event.

Film (band)

Film was a Yugoslav rock group founded in 1978 in Zagreb. Film was one of the most popular rock groups of the former Yugoslav new wave in the late 1970s to early 1980s.

History

New wave years (1979-1981)

During 1977 and 1978, bassist Marino Pelajić, guitarist Mladen Jurčić, and drummer Branko Hromatko were Azra members when Branimir "Johnny" Štulić brought Jura Stublić as the new vocalist. Stublić was to become Aerodrom member, but due to his deep vocals it never happened. The lineup functioned for a few months only and after a quarrel with Štulić, on early 1979, Pelajić, Jurčić, Hromatko and Stublić formed the band Šporko Šalaporko i Negove Žaluzine, naming the band after a story from the "Polet" youth magazine, which was soon after renamed to Film. The memories of the Azra lineup later inspired Štulić to write the song "Roll over Jura" released on Filigranski pločnici in 1982.

Saxophonist Jurij Novoselić, who at the time had worked under the pseudonym Kuzma Videosex, joined the band, inspiring others to use pseudonym instead of their original names: vocalist Stublić became Jura Jupiter, bassist Pelajić became Mario Baraccuda and guitarist Jurčić became Max Wilson. Before joining the band, Stublić did not have much experience as a vocalist, however, since his father had been an opera singer, he often visited the theatre and opera, and at the age of 13, he started playing the guitar, earning money as a street performer at seaside resorts.

Film is a 1965 film written by Samuel Beckett, his only screenplay. It was commissioned by Barney Rosset of Grove Press. Writing began on 5 April 1963 with a first draft completed within four days. A second draft was produced by 22 May and a forty-leaf shooting script followed thereafter. It was filmed in New York in July 1964.

Beckett’s original choice for the lead – referred to only as “O” – was Charlie Chaplin, but his script never reached him. Both Beckett and the director Alan Schneider were interested in Zero Mostel and Jack MacGowran. However, the former was unavailable and the latter, who accepted at first, became unavailable due to his role in a "Hollywood epic." Beckett then suggested Buster Keaton. Schneider promptly flew to Los Angeles and persuaded Keaton to accept the role along with "a handsome fee for less than three weeks' work."James Karen, who was to have a small part in the film, also encouraged Schneider to contact Keaton.

The filmed version differs from Beckett's original script but with his approval since he was on set all the time, this being his only visit to the United States. The script printed in Collected Shorter Plays of Samuel Beckett (Faber and Faber, 1984) states:
